Dear @nerd , team,
if one selects the right update channel, OTA updates will work as desired 
So switching to “test” update channel has allowed me to install 4.010, so I’m arrived at beta via OTA without any issue regarding update.
Primary findings in my first beta:
.
Between 4.005, 4.008 and 4.010 the reboot capability disappeared - I currently have to switch power line off for rebooting.
System halts with red led on if I select restart from menu.
Reboot from terminal console window works - this time in a proper speed… (was 3-4 mins slow with 4.005, was not able to produce logs, because system was not reachable during reboot, sorry)
It is still not possible to me to connect my Bluetooth remote - despite bluetoothctl shows more than in 4.005, but not my adapter.
One of the two rotary encoders is not working correct: Interesting enough only rotation on the first encoder needs tons of rotation to produce a single event.
Rotation signals (A/B) are connected to GPIO 22 and 27 in my installation. Because this has worked minutes ago, I cannot imagine a hardware failure.
(HW) Config:
Pi5,
Raspi 2 Display (DSI),
Two rotary encoders on several GPIOs
NO BT remote
Testing:
-
Spotify plugin, works (my only use case).
-
Touch display (and corresponding plugin) works
-
“Now Playing” plugin works
-
Rotary encoders are working with exception of proper rotation detection on GPIO 22/27
-
WiFi is working (can access from laptop / phone).
-
BT remote is NOT working
Regards,
Ralf
